We're looking into a some of the various things mentioned on this thread and others, for an upcoming PTR build:
--We understand the complaint about losing your 精华之泉
channel due to movement, now that it has a cooldown. Going straight to "Essence Font can always be cast while moving" is still the sort of thing we want to be careful about. Cast-while-moving isn't something that should proliferate too much outside of special buffs or spells that have that as a main purpose, but it's an option that we may try out on PTR.
--We'll buff Life Cocoon to better account for the large HP inflation in Legion.
--We're going to try a version of 碧愈疾风
that no longer has the 精华之泉
hook, and is much more efficient simply based on its own healing. That likely means making it cheaper rather than stronger, and probably means a longer cooldown or duration than what it has now. Both so that it's less disruptive by using fewer GCDs, and so that it's not a limitless way of pouring mana into smart healing. It should be a basic rotational option for a constant healing boost, with a positional factor.
--We're going to buff 升腾之雷
, initially simply using the same knob as in beta of changing 旭日东升踢
's cost. That version of fistweaving was generally popular (among the crowd that wants something with that much complexity), and possibly only fell away because it was never tuned back up enough to account for the loss of the beta version of Black Flame.
Our overall approach to Mistweaver in 7.2.5 is more focused on looking at specific issues like these, rather than any kind of deep overhaul. We also expect that the overall package of changes so far effects an increase to the total healing power of the spec (which was intended), and of course can do further tuning as we get a more solid idea of how much that is.
